Engine idles a little rough, used to be very inconsistent.
issue I'm still having is it sputters when I accelerate. I was thinking it might be an issue with fuel filter or fuel pump? possibly the fuel injection? Is there anything else that might be an issue?

 

could be a bad spark plug or wire check for any arc from the wires when dark out could also be rotor or cap , if it is one of these use ac delco parts, could also be a vacume hose, but I would lean towards ignition parts listed abouve
